The WD&WL adjustable wrench is a classic, heavy-duty hand tool forged from premium quality steel, designed for professionals and DIY users across construction, plumbing, automotive, and industrial maintenance. Available in two finish options — electroplated (Style A) and phosphated (Style B) — and ranging from 100mm to 750mm, this wrench series covers virtually every fastening application from small electronics to large industrial pipelines.
2. Key Features
Premium Quality Steel Forged Construction
The entire wrench body is forged from high-grade quality steel in a single piece, ensuring maximum structural integrity, strength, and resistance to bending or breaking under heavy loads. No welded joints or weak points.
High-Precision Worm Gear — Smooth Adjustment
The precision-machined worm gear and adjusting nut mechanism delivers smooth, effortless jaw adjustment with minimal backlash. Lock securely on nuts and bolts of any size within the opening range, with a tight, slip-free grip every time.
Laser-Etched Scale on Jaw
Laser-etched measurement markings on the adjustable jaw enable quick and accurate size identification of bolts, nuts, and fittings. Simply open the jaw around the fastener and read the scale directly — no need to carry a separate measuring tool.
Full-Body Heat Treatment — 30% Beyond ASME Standard
Every wrench undergoes complete heat treatment throughout the entire body, significantly enhancing hardness, toughness, and fatigue resistance. The resulting torque capacity exceeds the American ASME standard by more than 30%, providing an extra safety margin for demanding professional applications.
Two Finish Options — Electroplated & Phosphated
-
Style A (Electroplated): Bright, corrosion-resistant chrome finish. Ideal for general-purpose use, easy to clean, and visually appealing for retail display.
-
Style B (Phosphated): Dark phosphate coating provides excellent rust and corrosion resistance, especially suited for humid environments, outdoor work, and industrial settings. The matte finish also reduces glare.
Wide Size Range — 100mm to 750mm
Nine size options from compact 100mm to heavy-duty 750mm, with maximum jaw openings from 13mm to 85mm. One series covers every application scenario.

8. FAQ
Q1: What is the difference between Style A (Electroplated) and Style B (Phosphated)?
A: Style A features a bright chrome electroplated finish, offering good corrosion resistance and a clean appearance ideal for retail display and general-purpose indoor use. Style B has a dark phosphate coating that provides superior rust and corrosion resistance, making it better suited for humid environments, outdoor work, and heavy industrial applications. Both styles share the same forged steel construction and precision jaw mechanism.
Q2: What does “torque exceeds ASME standard by 30%” mean?
A: The American Society of Mechanical Engineers (ASME) sets minimum torque and strength standards for hand tools. Our wrenches undergo full-body heat treatment that increases their torque capacity to more than 130% of the ASME minimum requirement. This means the wrench can withstand significantly higher force before deforming or failing, providing an extra safety margin for professional and heavy-duty use.
Q3: What does the laser-etched scale on the jaw do?
A: The laser-etched measurement markings on the adjustable jaw allow you to quickly determine the size of the bolt, nut, or pipe you are working with. Simply open the jaw around the fastener and read the scale directly — no need to carry a separate caliper or ruler. This speeds up work and improves accuracy on the job site.
Q4: Which size should I choose for my needs?
A: Here is a quick guide:
- 100mm–150mm: Small fasteners, electronics, appliances, light DIY tasks.
- 200mm–250mm: General household, plumbing, automotive repair.
- 300mm–375mm: Medium-duty construction, pipefitting, industrial maintenance.
- 450mm–600mm: Heavy construction, large pipe valves, structural work.
- 750mm: Extra-heavy-duty for large pipeline valves, oil & gas equipment, and major industrial fittings.
Q5: Is this wrench suitable for professional/industrial use?
A: Absolutely. The full-body heat treatment, premium steel forging, and torque capacity exceeding ASME standards by 30%+ make this wrench series suitable for professional and industrial applications. It is widely used by construction workers, plumbers, mechanics, pipeline technicians, and maintenance crews.
Q6: Do you support OEM/ODM orders?
A: Yes! We offer comprehensive OEM and ODM services including custom logo engraving/stamping, branded packaging (color box, blister pack, hang-tag), handle color and finish options, and custom size specifications. Minimum order quantities apply — contact our sales team for details.
Q7: What is the minimum order quantity (MOQ)?
A: Standard MOQ starts at one full carton. Carton quantities vary by size:
- 100mm: 200 pcs/carton
- 150mm–200mm: 120 pcs/carton
- 250mm–300mm: 36–60 pcs/carton
- 375mm–450mm: 12–20 pcs/carton
- 600mm–750mm: 3–6 pcs/carton
For OEM/ODM orders, MOQ may vary. Contact us for the latest pricing and MOQ details.
Q8: How long is the delivery time?
A: Standard orders: 15–25 days after order confirmation. OEM/ODM orders may require additional time for mold setup, custom packaging, and logo production. Rush orders can be discussed on a case-by-case basis.
Q9: What is your payment term?
A: We typically accept T/T (30% deposit, 70% before shipment), L/C at sight, and other negotiable terms for established customers. PayPal and Western Union are available for sample and small orders.
Q10: Can I get a sample before placing a bulk order?
A: Yes, samples are available for quality evaluation. Sample costs and shipping fees apply but are typically refundable or credited against future bulk orders. Contact our sales team to arrange samples.
Q11: Can I order both styles (electroplated and phosphated) in one shipment?
A: Yes! You can mix styles and sizes within your order. Many customers order both finishes to cater to different market segments — electroplated for retail and general use, phosphated for industrial and outdoor applications. Mixed container loads are welcome.
Q12: What is the maximum jaw opening across all sizes?
A: The maximum jaw opening ranges from 13mm (100mm wrench) to 85mm (750mm wrench). The 750mm model (WB-41B-30) with its 85mm opening is designed for the largest industrial nuts, pipeline valves, and heavy-duty fasteners.
